The accuracy of the corrections applied in this work depends on how well the measured track properties are reproduced by the MC simulations.
The systematic uncertainties related to a possible disagreement were estimated by varying the track-selection criteria in reasonable ranges.
A detailed list of those track quality criteria and their variations can be found in previous ALICE publications [1]}, [2]}.
In order to estimate the systematic uncertainty related to the particle-composition correction, the yields of identified particles are varied within their respective systematic uncertainties and the extrapolation of those spectra to \(p_{\mathrm {T}} = 0.15{~\mathrm {GeV}}/c \)  is performed with different functions.
In addition, an uncertainty for the accuracy of the unfolding procedure is assigned that is quantified by the level of agreement between the unfolded simulated measurement and the expected distributions produced by the generator (MC closure test).
For each variation, the fully corrected results are calculated and their deviation to the nominal result is considered an uncertainty. Therefore, any effect of the variations on the performance of the analysis procedure is included in the respective systematic uncertainty.
To obtain the overall systematic uncertainties, all individual contributions are assumed to be fully uncorrelated and are added in quadrature.
